Product Introduction
When precise counting and event processing are critical in industrial automation, the Schneider TSXCTZ2A Counter modules deliver reliable performance. Part of the Modicon TSX Micro automation platform, this module provides two dedicated counting inputs for monitoring incremental signals, flow meters, or position encoders in manufacturing environments. Its compact design integrates seamlessly into existing TSX Micro racks, offering a straightforward solution for low-speed counting applications up to 40 Hz.
Technical Specifications Breakdown
The TSXCTZ2A operates with a counting frequency of 40 Hz and a network frequency of 100 Hz, making it suitable for moderate-speed counting tasks. It accepts input voltages of 24 V DC and 5 V DC, with defined voltage limits: 19...30 V for 24 V DC and 5.5 V for 5 V DC. The input current is 18 mA, and the module consumes 15 mA from the sensor power supply, which is < 2.5 V. Response times are 1.5 ms for event processing and 8 ms for the master task, ensuring timely data capture. The input type is resistive for 24 V DC, compatible with 2-wire/3-wire proximity sensors. Logic input is positive, and input impedance values are specified for both voltage levels: 0.27 Ohm at Un for 5 V DC and 1.4 Ohm at Un for 24 V DC.
Industry Applications
In packaging lines, the TSXCTZ2A counts products passing a sensor, triggering downstream actions like diverting or labeling. For example, a beverage bottling plant uses this module to tally bottles per minute, ensuring accurate batch counts. In material handling, it monitors conveyor belt rotations via a proximity sensor, providing feedback for speed control or jam detection. The module's 40 Hz counting frequency suits these moderate-speed processes, while its positive logic input simplifies integration with standard PLC outputs.
Installation & Setup Guidance
Mount the TSXCTZ2A into a free slot on the Modicon TSX Micro backplane, ensuring proper alignment with the rack's guide rails. Connect the 24 V DC or 5 V DC power supply according to the voltage limits specified: 19...30 V for 24 V DC and 5.5 V for 5 V DC. Wire the counting inputs using shielded twisted-pair cables to minimize electrical noise, especially in industrial environments with motors or drives. For 2-wire proximity sensors, connect the sensor's output directly to the input terminal; for 3-wire sensors, also connect the common and power lines. Verify the input state thresholds: state 1 requires ≥ 11 V for 24 V DC and ≥ 2.4 V for 5 V DC; state 0 requires ≤ 5 V for 24 V DC and ≤ 1.2 V for 5 V DC. Use the module's 1.5 ms event response time for time-critical counting tasks.
Maintenance & Reliability
Regularly inspect the TSXCTZ2A for dust accumulation on the front panel and connectors, as debris can affect signal integrity. Check the input voltage levels with a multimeter to ensure they stay within the specified limits (19...30 V for 24 V DC, 5.5 V for 5 V DC). Monitor the module's current consumption (15 mA) to detect early signs of component degradation. In high-vibration environments, verify that the module is securely fastened to the rack. The module's resistive input type for 24 V DC provides stable performance, but periodic testing of connected sensors helps prevent false counts.
Compatibility & Integration
The TSXCTZ2A is designed for the Modicon TSX Micro automation platform, integrating directly with TSX Micro processors and I/O modules. It supports positive logic input, which aligns with standard PLC programming conventions. The module's two counting inputs can be configured via the PLC software for up/down counting or frequency measurement. It is compatible with 2-wire and 3-wire proximity sensors operating at 24 V DC, as well as other dry contact or NPN/PNP sensors meeting the input voltage and current thresholds.
Selection Guide & Purchasing Advice
Before purchasing the TSXCTZ2A, verify that your Modicon TSX Micro rack has an available slot and that the power supply can handle the additional 15 mA current draw. Confirm the counting frequency requirement of your application does not exceed 40 Hz. For applications needing higher speeds, consider alternative modules.
